前文提要
最近大家是不是都有那种危机感，项目变多了，工时压紧了，老板说，我不管你加不加班，我只看结果，项目经理说，我不管你用什么技术栈，我只要没BUG，测试说，交互不管好不好，我们只要搞光速推塔。你心说？那我走？
大家也发现了，以前要很多行代码才能实现的功能，现在变得格外简单，原因很多大佬开源了很多项目，很多大厂平台供我们选择，从此，无止尽的C+V操作变成了拼技术选型，拼方向，别人一行代码搞定的事情，一个类生成CRUD，你要不停的拷拷拷，BUG多数全凭心情，那为什么不选择一款开箱既用的产品呢？
功能概述
使用 Apache License 2.0 协议，源代码完全开源，无商业限制
| 代码生成器 | VS | Erupt |
|---|---|---|
| 前端 + 后端 7 ~ 10 个文件 | 文件数量 | 仅需一个类文件 |
| 重新生成代码或修改已生成代码 | 修改字段 | 添加字段注解 |
| 需要手动执行建表 SQL | 建表语句 | 自动建表 |
| 需要整个工程，模块众多不好管理 | 初次部署 | 仅需引入 Jar 依赖即可，基础数据自动生成 |
| 需要熟悉代码生成器所提供的前端 API，有一定学习成本 | 前端代码 | 零前端代码 |
| 传统分层调用的方式开发 | 开发方式 | 全注解式开发 |
| 仅支持基本的数据组件复杂的组件需自定义 | 组件支持 | 支持23类表单组件，且支持一对多，多对多等复杂关系组件 |
| 一般只支持 MySQL | 数据库 | 支持 MySQL、Oracle、PostgreSQL、H2 等所有主流数据库 |
| 需要生成大量代码复制到项目中，功能越多维护成本越高 | 开发时间 | 仅需一个后端工程师，短时间就可以完成高质量后台管理系统 |
| Java 代码 | 逻辑扩展 | 按需 @DataProxy 实现 |
| 表数量越多启动越慢 | 启动速度 | 百张表映射毫秒级初始化 |
import: 支持多数据源：
并且：项目内置了很多功能无需开发，开箱即用
简单实力
简单CRUD
@Erupt(
name = "简单的例子",
power = @Power(importable = true, export = true)
)
@Table(name = "t_simple") //数据库表名
@Entity
public class Simple extends BaseModel {
@EruptField(
views = @View(title = "文本"),
edit = @Edit(title = "文本", notNull = true, search = @Search)
)
private String input;
@EruptField(
views = @View(title = "数值", sortable = true),
edit = @Edit(title = "数值", search = @Search)
)
private Float number;
@EruptField(
views = @View(title = "布尔"),
edit = @Edit(title = "布尔", search = @Search)
)
private Boolean bool;
@EruptField(
views = @View(title = "时间"),
edit = @Edit(title = "时间", search = @Search(vague = true))
)
private Date date;
@EruptField(
views = @View(title = "滑动条"),
edit = @Edit(title = "滑动条", type = EditType.SLIDER, search = @Search,
sliderType = @SliderType(max = 90, markPoints = {0, 30, 60, 90}, dots = true))
)
private Integer slide;
@EruptField(
views = @View(title = "下拉选择"),
edit = @Edit(
search = @Search,
title = "下拉选择", type = EditType.CHOICE,
choiceType = @ChoiceType(fetchHandler = SqlChoiceFetchHandler.class,
fetchHandlerParams = "select id,name from e_upms_menu"
)
)
)
private Long choice;
}像这种带有CRUD功能的表单，只需要这样几行代码，一个文件就可以了
那你选择写Controller、Service、Dao、View + HTML语法，还是写这几行代码呢？
简单上传附件
@Column(length = 120)
@EruptField(
views = @View(title = "附件",
type = ViewType.ATTACHMENT),
edit = @Edit(title = "附件", type = EditType.ATTACHMENT,
attachmentType = @AttachmentType(fileTypes = {"PDF","PNG","JPEG","ZIP"}, maxLimit = 1))
)
private String fileUrl;这是给你封装好的上传附件组件，无需其他代码，非常好用
一对多级联
@ManyToMany
@JoinTable(
name = "COMMON_ZY_SZHJXZY",
joinColumns = {@JoinColumn(
name = "zbid",
referencedColumnName = "id"
)},
inverseJoinColumns = {@JoinColumn(
name = "ywid",
referencedColumnName = "id"
)}
)
@EruptField(
edit = @Edit(
title = "仿真实习实训软件面向专业",
type = EditType.TAB_TABLE_REFER,
notNull = true,
search = @Search(vague = true)
),
sort = 45
)
private Set<ZyjsZyszView> zyjsZyszs;高级用法
如果你的数据源不是项目链接的单标，是从接口或者其他库获得的，我们可以采用多数据源
代码实力
//注入启动类
@Bean
public ApplicationRunner appRunner() {
return new ApplicationRunner() {
@Override
public void run(ApplicationArguments args) throws Exception {

}
};
}实体类
@Erupt(

desc = "本年度活动表"
)

@Column(length = 400)
@EruptField(
